摘要

Essentially longitudinal fibres (1) are continuously wound both around a cylindrical core tube (4) and around a metallic nozzle having the shape of a double cone, engaged over the core tube, reversing the direction of the winding on spikes (9) distributed over a ring (8) positioned on a threaded portion (11) extending the nozzle, and these longitudinal fibres are then heaped with circumferential fibres (7) before carrying out final polymerisation of the tube. <??>Application to composite tubes for oil prospecting at sea.
